Buying Guide
- Power capacity: Choose VA/W ratings based on your critical load. Higher wattage supports more devices during longer outages.
- Output waveform: Pure sine wave is best for sensitive electronics; simulated sine wave suffices for basic devices.
- Outlets and layout: Ensure enough battery-backed outlets for essential gear and consider spacing for bulky plugs.
- Battery type and lifespan: Lead-acid offers lower upfront cost; LiFePO4 provides longer life and lower total cost of ownership.
- Management features: LCD/LED status, AVR, USB charging, and remote monitoring improve reliability and ease of use.
- Networking and expandability: Some units support remote control, software shutdowns, or modular battery packs for future growth.
- Physical footprint and noise: Compact designs save space; consider cooling and fan noise in quiet environments.
